Many, many folks with the G41 chipset are affected by this missing DRI support. The desktop graphic performance is unacceptable without it. Any idea what is involved to provide it?
Why does glxinfo report direct rendering anyhow under g41?

I'm running 3 DG41TY Fedora 10 computers with the G41 graphics chipset. I've patched the kernel with https://bugzilla.redhat.com/attachment.cgi?id=337490 and 3D/compiz works fine.
However all of the systems hard lock whenever X is restarted after a random delay (i.e. X starts fine the first time (most of the time), but on the first or second logout, the system hangs with no response to pings, etc.).
I suspect this is why the patch hasn't made it into the mainline kernel. Is there anything I (or anybody else) can do to help track down the problems so this can get enabled?

We believe this common bug has been fixed, as multiple people have confirmed this.
